Review on 📻 HAM Equipment Balun Kit NXO-100 for 1-30Mhz Shortwave Radio: Magnetic Balance for Enhanced Performance of Amateur Radio Antennas - DIY by Douglas First

I had to look at pictures from the Revain website to connect. It was hard to tell from the pictures on the website but I figured it out. Two of the four screw holes that attach the coax cable to the unit had to be enlarged to accommodate the nuts on the screws as they are too close to the bottom of the case. If the body was 1/8 inch lower it wouldn't be a problem. In terms of water resistance, rubber washers can be used to seal the screws as well as the coaxial connector. Otherwise the device works and I saved some money.
